I proposed a slice��in the inbox for this.

- added RPackage>>removeFromSystem
�� - this version removes defined classes and also extension methods defined in the package.
- make Nautilus ask the RPackage to remove itself (instead of doing it in the UI)

I tested it with the fileout of a package with extension methods, removing the package and filing it in again.
